An 11-year linezolid-resistant Staphylococcus capitis clone dissemination with a similar cfr-carrying plasmid in China

Linezolid resistance has represented a global concern with its wide dissemination among nosocomial pathogens in recent years. One hundred and two linezolid-resistant Staphylococcus capitis (LRSC) were constantly isolated from 2011 to 2021, which demonstrated single clonal dissemination in a Chinese...

description Linezolid resistance has represented a global concern with its wide dissemination among nosocomial pathogens in recent years. One hundred and two linezolid-resistant Staphylococcus capitis (LRSC) were constantly isolated from 2011 to 2021, which demonstrated single clonal dissemination in a Chinese tertiary hospital. A structurally similar cfr-carrying plasmid was identified among 90 isolates. A chromosomal cfr was located beside a Tn4001-like transposon and ISEnfa4 in one strain (LR95). The loss of cfr-carrying plasmid was observed in 11 isolates and the in vitro passage experiments. Conjugation experiments demonstrated the horizontal transferability of the cfr-carrying plasmid into Staphylococcus aureus RN4220. Both cfr-positive LRSC and S. aureus showed no significant differences in growth rates, while only the former displayed competition defect, suggesting this plasmid imposed a certain fitness cost on LRSC. Hence, ongoing measurements are supposed to be adopted to control the spread of these antimicrobial-resistant bacteria.
